<p><b>Syntax</b></p><blockquote>
Result = <font color="#006666"><b>IsRegularExpression</b></font>(#RegularExpression)</blockquote>

</blockquote>
<b>Description</b><br><blockquote>

Tests if the given #RegularExpression number is a valid and correctly initialized, regular expression. 

</blockquote><p><b>Parameters</b></p><blockquote>
<style type="text/css">
table.parameters { border-spacing: 0px; border-style: none; border-collapse: collapse; }
table.parameters td { border-width: 1px; padding: 6px; border-style: solid; border-color: gray; vertical-align: top; font-family:Arial; font-size:10pt; }
</style>
<table width="90%" class="parameters">
<tr><td width="10%"><i>#RegularExpression</i></td>
<td width="90%"> 
The regular expression to use. 

</td></tr>
</table>
</blockquote><p><b>Return value</b></p><blockquote>

Returns nonzero if #RegularExpression is a valid regular expression and zero otherwise. 

</blockquote><p><b>Remarks</b></p><blockquote>

This function is bulletproof and can be used with any value. If the 'Result' is not zero then the object is valid and 
initialized, otherwise it will equal zero. This is the correct way to ensure a regular expression is ready to use.
